Layout overhaul

Various locale keys have been added for navigation text (see the changes in the github commit)

Added 'Select Role' and 'Select Press' block plugins

Added omp/styles/omp.css file which contains references to all CSS files used. This file is the only CSS file needed to be referenced in omp/templates/common/header.tpl. The existing CSS files have been modified (see the changes on github)

All javascript is being called in /templates/common/header.tpl. This means that the jQuery plugin is no longer in use. In the future we will be using Google's CDN to call jQuery and jQueryUI, and eventually other libraries.

New container divs have been added to header.tpl, and leftSidebar/rightSidebar code has been removed. (see the changes on github for exactly what to change)

A new breadcrumb file has been added in omp/templates/common/breadcrumbs.tpl--This should be able to be copied directly over (or eventually abstracted into pkp-lib)

/omp/templates/common/footer.tpl was added to include closing tags for new divs added to header.tpl. When all of the application's UIs are in sync, this can be abstracted to pkp-lib.

Various CSS and Javascript libraries have been added to allow for new UI features, as well as new images

Listbuilders

For form elements that involve simple manipulation of lists (like masthead user lists in all apps), the MVC structure of modifying this data can be compacted into a listbuilder handler located in controllers/listbuilder/. There are three source data types of listbuilders that can be used, here are some examples:

Free-text entry (for adding new data to the system)--See /controllers/listbuilder/AuthorRolesListbuilderHandler.inc.php

Drop-down list selection (for adding already-existing data to a new group or classification)--See /controllers/listbuilder/InternalReviewRolesListbuilderHandler.inc.php
